.Sh DESCRIPTION
|
||||
The
|
||||
.Fn sigwait
|
||||
function selects a set of signals, specified by
|
||||
.Fa set .
|
||||
If none of the selected signals are pending,
|
||||
.Fn sigwait
|
||||
waits until one or more of the selected signals has been generated.
|
||||
Then
|
||||
.Fn sigwait
|
||||
atomically clears one of the selected signals from the set of pending signals
|
||||
for the process and sets the location pointed to by
|
||||
.Fa sig
|
||||
to the signal number that was cleared.
|
||||
.Pp
|
||||
The signals specified by
|
||||
.Fa set
|
||||
should be blocked at the time of the call to
|
||||
.Fn sigwait .
|
||||
.Sh RETURN VALUES
|
||||
If successful,
|
||||
.Fn sigwait
|
||||
returns 0 and sets the location pointed to by
|
||||
.Fa sig
|
||||
to the cleared signal number.
|
||||
Otherwise, an error number is returned.
|

to the location pointed to by the second function parameter.

|

Condition attribute objects are used to specify parameters to
|
||||
.Fn pthread_cond_init .
|
||||
FreeBSD's implementation of conditions does not support any non-default
|
||||
attributes, so these functions are not very useful, though they are required to
|
||||
to be present by POSIX.
|
||||
|
||||
The
|
||||
.Fn pthread_condattr_init
|
||||
function initializes a condition attribute object with the default attributes.
|
||||
|
||||
The
|
||||
.Fn pthread_condattr_destroy
|
||||
function destroys a condition attribute object.
|
||||
.Sh RETURN VALUES

Otherwise, an error number is returned to indicate the error.

.Fd #include <signal.h>

||||
.Fn sigwait "const sigset_t *set" "int *sig"
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Fn sigwait
|
||||
function selects a set of signals, specified by
|
||||
.Fa set .
|
||||
If none of the selected signals are pending,
|
||||
.Fn sigwait
|
||||
waits until one or more of the selected signals has been generated.
|
||||
Then
|
||||
.Fn sigwait
|
||||
atomically clears one of the selected signals from the set of pending signals
|
||||
for the process and sets the location pointed to by
|
||||
.Fa sig
|
||||
to the signal number that was cleared.
|
||||
.Pp
|
||||
The signals specified by
|
||||
.Fa set
|
||||
should be blocked at the time of the call to
|
||||
.Fn sigwait .
|
||||
.Sh RETURN VALUES
|
||||
If successful,
|
||||
.Fn sigwait
|
||||
returns 0 and sets the location pointed to by
|
||||
.Fa sig
|
||||
to the cleared signal number.
|
||||
Otherwise, an error number is returned.
|
||||
.Sh ERRORS
|
||||
.Fn sigwait
|
||||
will fail if:
|
||||
.Bl -tag -width Er
|
||||
.It Bq Er EINVAL
|
||||
.Fa set
|
||||
specifies one or more invalid signal numbers.

.Sh DESCRIPTION
|
||||
Thread attributes are used to specify parameters to
|
||||
.Fn pthread_create .
|
||||
One attribute object can be used in multiple calls to
|
||||
.Fn pthread_create ,
|
||||
with or without modifications between calls.
|
||||
|
||||
The
|
||||
.Fn pthread_attr_init
|
||||
function initializes
|
||||
.Fa attr
|
||||
with all the default thread attributes.
|
||||
|
||||
The
|
||||
.Fn pthread_attr_destroy
|
||||
function destroys
|
||||
.Fa attr .
|
||||
|
||||
The
|
||||
.Fn pthread_attr_set*
|
||||
functions set the attribute that corresponds to each function name.
|
||||
|
||||
The
|
||||
.Fn pthread_attr_get*
|
||||
functions copy the value of the attribute that corresponds to each function name
|
||||
to the location pointed to by the second function parameter.
|
||||
|
||||
.Sh RETURN VALUES
|
||||
If successful, these functions return 0.
|
||||
Otherwise, an error number is returned to indicate the error.
|
||||
.Sh ERRORS
|
||||
.Fn pthread_attr_init
|
||||
will fail if:
|
||||
.Bl -tag -width Er
|
||||

||||

|

|

||||
.Fn pthread_attr_destroy

.Bl -tag -width Er
|

|

|

.Sh DESCRIPTION
|
||||
Condition attribute objects are used to specify parameters to
|
||||
.Fn pthread_cond_init .
|
||||
FreeBSD's implementation of conditions does not support any non-default
|
||||
attributes, so these functions are not very useful, though they are required to
|
||||
to be present by POSIX.
|
||||
|
||||
The
|
||||
.Fn pthread_condattr_init
|
||||
function initializes a condition attribute object with the default attributes.
|
||||
|
||||
The
|
||||
.Fn pthread_condattr_destroy
|
||||
function destroys a condition attribute object.
|
||||
.Sh RETURN VALUES
|
||||
If successful, these functions return 0.
|
||||
Otherwise, an error number is returned to indicate the error.
|

|

.Sh DESCRIPTION
|
||||
Condition attribute objects are used to specify parameters to
|
||||
.Fn pthread_cond_init .
|
||||
FreeBSD's implementation of conditions does not support any non-default
|
||||
attributes, so these functions are not very useful, though they are required to
|
||||
to be present by POSIX.
|
||||
|
||||
The
|
||||
.Fn pthread_condattr_init
|
||||
function initializes a condition attribute object with the default attributes.
|
||||
|
||||
The
|
||||
.Fn pthread_condattr_destroy
|
||||
function destroys a condition attribute object.
|
||||
.Sh RETURN VALUES
|
||||
If successful, these functions return 0.
|
||||
Otherwise, an error number is returned to indicate the error.
|
||||
.Sh ERRORS
|

.Fn pthread_condattr_init

.Sh DESCRIPTION
|
||||
The
|
||||
.Fn pthread_sigmask
|
||||
function examines and/or changes the calling thread's signal mask.

If
|

is not
|
||||
.Dv NULL ,
|
||||
it specifies a set of signals to be modified, and

specifies what to set the signal mask to:
|
||||
.Bl -tag -width SIG_UNBLOCK
|
||||
.It Dv SIG_BLOCK
|
||||
Union of the current mask and
|
||||
.Fa set .
|
||||
.It Dv SIG_UNBLOCK
|
||||
Intersection of the current mask and the complement of
|

.Fa set .
|
||||
.It Dv SIG_SETMASK
|
||||
.Fa set .
|
||||
.El
|

.Pp
|
||||
If
|
||||
.Fa oset
